TMI BLOOD!

So my period is 32 days late. I took plan b April 25th and 30th, I know plan b fucks up cycles especially twice in a week. Do.not.tell.me.that 🗣🗣🗣 I started light pink and brown spotting Friday (when eve says a new period should’ve started) and now it’s getting a little darker and more mucus like. I’ve taken multiple tests and all have been negative and ive been on birth control for a couple weeks now. Could this be a weird period from the plan b? Side effect of birth control? My obgyn can’t see me until next month and won’t order a blood test until seeing me and I don’t have time to sit at the emergency room and wait for their dr to order a blood test. I just wanna know if y’all think I should just suck it up and sit at the er or if this could be a period. I mentally cannot handle a pregnancy so don’t be fucking assholes 😊
